A combination of a grey water harvesting
system and low-flow fixtures ensures 40% savings
in water consumption. High-performance façades
and reflective roof finishes reduce the cooling load
on the HVAC system and (in addition to efficient Air
Cooled chillers) contribute to 27% energy savings
against the ASHRAE baseline.
Of course, one of the most effective ways to
manage a building’s energy consumption is to
ensure that it is properly insulated. Energy models
were run at the beginning of the project’s design
phase and were used to inform the specification
of the building’s façades. Double-glazing, together
with sun louvres and air-tightness tests, was
employed to ensure that the building was designed
relative to its specific micro-climate. The end result
was not only a reduced load on the building’s
systems but also vastly improved comfort levels
for the building’s end-user.
Alternative transport facilities such as bicycle
racks and a well-connected public transport
network encourages occupants to reduce their
carbon footprint. Occupant health and well-being
is ensured with the use of low VOC coatings
and nearly 30% higher fresh air rate above the
SANS guideline.
Lastly, resource efficiency is ensured through
the use of local materials with a high recycled value
and zero-ODP refrigerant based chillers achieve
reduced emissions.
